Answer:
Step-by-step explanation:  3root5x^2 + 25x - 10root5 = 0
3xroot5 + 25x - 10root5 = 0      [ root x^2 = x]
28x root5 = 10 root5         [ -10root5 turns to 10 root5 when transferred to RHS]
28x root 5/root5 =10
28x=10
x = 10/28
x = 0.35

Answer:
25 in x 15 in
Step-by-step explanation:
Given:
- Length = 3/5 the width
- Area = 375 in²
Let width = 
Therefore, length = 3/5 
First create an equation for the area of the picture based on the given information for its width and length:

We are told the area of the enlarged picture is 375 in².  Therefore, substitute this into the equation and solve for  to find the width of the enlarged picture:
 to find the width of the enlarged picture:

Therefore, the width of the enlarged picture is 25 in.
Substitute the found value of  into the expression for length to find the length of the enlarged picture:
 into the expression for length to find the length of the enlarged picture:

Therefore, the dimensions of the enlarged picture are <u>25 in x 15 in</u>.  The width is 25 in and the length is 15 in, as the length is 3/5 of the width.
 
        
             
        
        
        
So far, this is shaping up to be a very interesting and engaging exercise. Now, what do you want done with the model ? To put it in other words, what is the question ? ? (Other than the fact that no real flight can fit this model.)
